This paper is considering the applicability of the surface wave method for understanding the geological profile under the riverbed. The profile of S-wave velocity and the N- value were well matched. Therefore, S-wave velocity in the ground of the river zone can be treated as an indicator similar to the N - value. It is reasonable estimate of the geological cross-sectional view by using the S-wave velocity distribution. In addition, the pseudo-three-dimensional distribution of S-wave velocity, was consistent with the local situation. As a results, the use of the S-wave velocity distribution obtained from the surface wave method, it is possible to create the 3D hazard map for riverbed degradation and improving the accuracy of the analysis model.
